Figure 2–3 Installer JDK Selection Screen

Select
the option labeled “Install and use the default version of the Java SDK.”

Choose an SDK already installed on your system.

The drop-down menu under the option “Choose a Java SDK from the list below” lists existing SDKs
found in standard locations on your system. You can use this option to specify
one of these SDKs for Message Queue to use.

Provide an explicit path to an existing SDK.

To use an SDK from a location other than the standard
ones, enter its path in the text field under the option “Type in a Java SDK location below,” or use the
button marked with an ellipsis (…)
to browse to it interactively.

Figure 2–4 Installer Multilingual Packages Screen

By
default, Message Queue is installed to operate in the English language only.
The Multilingual Packages screen allows you to install it for use in another
language.

If you will be using Message Queue in a language other than English,
select the checkbox labeled “Install Message Queue multilingual packages.”

If you will be using Message Queue only in English, leave this
checkbox deselected.

Caution –

If you choose not to install the multilingual packages and
later decide that you do need them after all, there is no convenient way to
install them incrementally: you will have to uninstall Message Queue and then
repeat the entire installation procedure with the multilingual packages selected.
Before proceeding to install without the multilingual packages, be sure you
will not be needing them in the future.

Figure 2–5 Installer Upgrade Screen

Specify whether to upgrade Message Queue and its shared components.

If an earlier version of Message Queue exists on your system, or if
any of the shared components on which Message Queue depends need to be upgraded
from earlier versions, the Upgrade screen displays them in a scrollable list
along with their current and required versions. If no upgrades are needed,
the existing components are simply listed with their version numbers and a
notation that they will remain at their current versions. In this case, the “Upgrade”
and “Do not upgrade” radio buttons do not appear; just click Next
to proceed to the next step.

Caution –

It is possible that upgrading Message Queue’s shared
components may break other software components on your system that depend
on the earlier versions previously installed. Be sure there are no such dependencies
before proceeding with the upgrade.

To proceed with the upgrade:

Make sure the radio button labeled “Upgrade” is selected.

If you instead select “Do not upgrade,” the Next
button becomes disabled; your only options at this point are Back (to return
to the previous screen) or Cancel (to exit the Installer without completing
installation).

Figure 2–8 Sun Connection Registration Screen

Register Message Queue with Sun Connection.

Sun Connection is
a Sun-hosted service that helps you track, organize, and maintain Sun hardware
and software. When you register a Message Queue installation with Sun Connection,
information such as the release version, host name, operating system, installation
date, and other such basic information is securely transmitted to the Sun
Connection database. The Sun Connection inventory service can help you organize
your Sun hardware and software, while the update service can inform you of
the latest available security fixes, recommended updates, and feature enhancements.

Registration requires that you have a Sun Online account or create
one. If you do not already have an account, the installer provides the following
screen (Figure 2–9)
for creating a Sun Online account:

Figure 2–9 Create Sun Online Account Screen

Note –

If you choose not to register Message Queue during installation,
you can subsequently register Message Queue by running the installer in register-only
mode, as follows:

# installer -r

The
register-only mode requires that Message Queue 4.2 already be installed
and will display only the installer screens related to registration.

When Sun Connection registration is complete, the Installer’s
Summary screen (Figure 2–10) appears,
summarizing the steps that were performed during installation.

Figure 2–10 Installer Summary Screen

You can click the links on this screen for a detailed summary report
and a log file giving more details on the installation.

Click the Exit button to dismiss the Summary screen.

Message Queue installation is now complete.

Tip –

After installation is complete, you can check that the expected
versions of Message Queue and the Java runtime have been installed by navigating
to the Message Queue /bin directory and executing the
command

imqbrokerd -version

The output from this command identifies the versions of Message Queue and
the Java SDK that are installed on your system.
